monitoring the mqtt broker revealed two bugs and one design dead-end:
1. the jellyfin-plugin-webhook publishes pascalcase fields
(NotificationType, ItemId, ItemType) and we were reading camelcase
(event, itemId, itemType). every real payload was rejected by the
first guard — the mqtt path never ingested anything.
2. the plugin has no ItemUpdated / Library.* notifications. file
rewrites on existing items produce zero broker traffic (observed:
transcode + manual refresh metadata + 'recently added' appearance
→ no mqtt messages). ✓✓ via webhook is structurally impossible.
fix the webhook path so brand-new library items actually get ingested,
and narrow ACCEPTED_EVENTS to just 'ItemAdded' (the only library-side
event the plugin emits).
move the ✓✓ signal from webhook-corroboration to post-execute ffprobe
via the existing verifyDesiredState helper: after ffmpeg returns 0 we
probe the output file ourselves and flip verified=1 on match. the
preflight-skipped path sets verified=1 too. renamed the db column
webhook_verified → verified (via idempotent RENAME COLUMN migration)
since the signal is no longer webhook-sourced, and updated the Done
column tooltip to reflect that ffprobe is doing the verification.

after ffmpeg finishes we used to block the queue on a jellyfin refresh
+ re-analyze round-trip. now we just kick jellyfin and return. a new
mqtt subscriber listens for library events from jellyfin's webhook
plugin and re-runs upsertJellyfinItem — flipping plans back to pending
when the on-disk streams still don't match, otherwise confirming done.
- execute.ts: hand-off is fire-and-forget; no more sync re-analyze
- rescan.ts: upsertJellyfinItem takes source: 'scan' | 'webhook'.
webhook-sourced rescans can reopen terminal 'done' plans when
is_noop flips back to 0; scan-sourced rescans still treat done as
terminal (keeps the dup-job fix from a06ab34 intact).
- mqtt.ts: long-lived client, auto-reconnect, status feed for UI badge
- webhook.ts: pure processWebhookEvent(db, deps) handler + 5s dedupe
map to kill jellyfin's burst re-fires during library scans
- settings: /api/settings/mqtt{,/status,/test} + /api/settings/
jellyfin/webhook-plugin (checks if the plugin is installed)
- ui: new Settings section with broker form, test button, copy-paste
setup panel for the Jellyfin plugin template. MQTT status badge on
the scan page.
